Abstract: We propose to follow up 29 short period (P < 1 month) planet candidates around F, G and K stars with V=7.4-11.2 using the high throughput Exoplanet Tracker (ET) Doppler instrument at the KPNO 2.1m telescope. We will continue to support public users to use ET for their independent high precision RV measurements. All of these candidates show radial velocity variations with an amplitude less than 700 m/s within 15 days. 23 of the planet candidates around V=7.4-9 bright stars were identified during an earlier planet survey of a total of 150 F, G and K dwarfs and subdwarfs using the Coude Feed 0.9 m/2.1m telescopes and ET in Dec. 04 to Jul. 06. The 6 candidates around V=10.1-11.2 relatively faint stars were identified from a trial planet survey using the newly commissioned multi-object Keck ET instrument at the Sloan 2.5m telescope. Our goal is to detect 5-10 short period planets and 1 transiting planet over the next observation year. We will continue monitoring 2 known planets with intermediate period (P~200-300 days) and 2 RV stable stars to measure the instrument long term stability, preparing us to support future detection of long period planets at Kitt Peak.
